Given you've had a whole selection of bits I'd hope that's a mistake vs being dodgy, be interesting to see what they say though.
On reflection, the items look like something you’d order for a hen do or similar to HOPEFULLY a mistake. They’ve asked me to return so they can investigate.
What’s annoying me is at the checkout it said ‘comes in original packaging’ but by default I often tick the ‘deliver in Amazon box’ or whatever as I use them for other things. Didn’t go to plan this time.
